The term marine generator can be somewhat misleading as many boats have marine batteries that are recharged by the motor or engine. Often, for these situations, inverters are used to convert from DC to AC for use with standard electronics. For some larger boats, in boat generators are used.
These are usually generators that are either powered by the boat’s engine or has a separate, dedicated engine that requires a water cooled system or a special air flow cooling system.
For the mainstream boater, the best generators for marine use are the standard portable, inverter generators. These are great for starting purposes or using onboard for powering devices and more.
Doesn’t Have To Be Dedicated Marine
It is true there are some dedicated marine generators but they are few and far between and are typically more expensive than standard portable, inverter generators. Compact, inverter generators are fine for marine use as they are also great for camping, tailgating, RV use and for residential use.
If you are avid fisherman or boater, a small inverter generator is perfect for your needs and it is great for when you need power.
Most inverter generators can also be used in parallel with each other(Usually only the same or larger models) thus giving you the opportunity to scale to your power needs.
Inverter generators supply extremely level power curves with the sine wave near perfect. This gives you utility grade power while you are away from shore if need be. It also means not having to worry about damaging any of your sensitive electronics on board.
Best of all, they are quieter than the standard generator and this can be a huge plus when fishing or just enjoying your boat. Additionally, they are very portable. Easy enough to load and unload from the boat and store so you can use it over and over again.
Five Great Generators For Marine Use

Best Long Running Compact Generator
The rabbit got tired of just batteries and has now joined the power production consumer market with this generator producing a 2.8K surge capacity. The Energizer Model #eZV2800 Generator has a continuous generation of 2.6K, so there is no problem with running out of power.
It is both electric start and manual, recoil start while the control panel is easy to read and use.
It has a low oil warning and shutoff and the unit has dual standard outlets as well as a twist lock connection for a transfer switch or RV connection. People who bought and used this generator love the easy starting, with both electric and recoil and how stable this unit is on its own footing.
Ultimate Inverter Generator for Marine Use
The Yamaha Model #EF2000iS inverter Generator is a top quality inverter generator with 2,000 Watts of surge capacity and 1,600 Watts of continuous generation. It has dual standard outlets and it is fully CARB and EPA compliant.
This generator is also among the most quiet generators and it features overload protection, low oil shut off and dual operating modes for fuel savings.
If you are looking for the perfect generator for you boat, this one is at the top of the list. People who use this generator speak very highly of both the quality of the unit and the delivery of the power at stable rates.
For the best results in power generation, be sure to consult your manual before operation. Never run a generator in an enclosed space to prevent fumes from building up and potentially causing injury or worse. Never attempt to put fuel in a hot generator or when it is running to prevent accidents.
